An audit is an independent examination of financial information or internal processes to ensure they are accurate, compliant, and trustworthy.
There are two main types of audits in accounting:
🔎 Internal Audit
🧾 External Audit
Both are essential, but they serve different purposes and are conducted by different people.
Conducted by: The company’s own employees (internal audit team or department)
Purpose: To help management improve internal controls, efficiency, and compliance
✅ Internal audits are preventive — they find and fix issues before they become serious.
Conducted by: Independent, third-party auditors (e.g., PwC, Deloitte)
Purpose: To provide an unbiased opinion on the accuracy of a company’s financial statements
✅ External audits are detective — they help verify and give credibility to financial info.
Let’s say your company is preparing its annual financial report.
Internal auditors check if:
Employees follow procedures 🔍
Transactions are recorded properly 🧾
Assets are protected 💼
External auditors then:
Test samples of transactions 📊
Verify balances in financial statements 💰
Provide an audit opinion in the annual report ✅
